Washing machine and control method thereof

Abstract

The invention belongs to the field of washing machines, and particularly discloses a washing machine. The washing machine comprises a plurality ofvariable frequency motors, a variable frequency board and a main control board, wherein the variable frequency board comprises a board body, a variable frequency control circuit and a plurality of mutually independent inverter circuits; the variable frequency control circuit and the plurality of mutually independent inverter circuits are integrated on the board body; the plurality of inverter circuits are connected with the variable frequency control circuit; the inverter circuits are connected with the variable frequency motors in a one-to-one correspondence manner; the main control board comprises a main control circuit; the main control circuit is connected with the variable frequency control circuit; and the main control circuit is used for sending a working instruction to the variable frequency control circuit, so that the variable frequency control circuit controls the variable frequency motors to execute corresponding work according to the working instruction. According to the washing machine, the control over the multiple variable frequency motors can be achieved through one variable frequency board, the operation of the multiple variable frequency motors is mutually independent, and the operation speed can be independently adjusted according to the operation requirement of a washing machine system.

Description

Technical field [0001] The present application belongs to the area of ​​the washing machine, which specifically involves a washing machine and a control method thereof. Background technique [0002] Traditional washing machines include multiple motors, but different motors require a variable frequency board to control, such as multi-blocks need to be installed separately, but the interior spatial position of the washing machine is limited, and the external interference is large, and each converter plate One way to control a motor is greatly increased. [0003] It should be noted that information disclosed in the above background technology is only used to enhance the understanding of the background of the present application, and therefore, it may include not constituting the prior art information known to those of ordinary skill in the art. Inventive content [0004] The purpose of this application is to provide a technical problem of a washing machine and a control method ther...

AI Technical Summary

Problems solved by technology

[0002] The traditional washing machine contains multiple motors, but different motors need to be controlled by a frequency conversion board. In this solution, multiple frequency conversion boards need to be installed separately, but the internal space of the washing machine is limited, and its external interference is large, and each frequency conversion board One-to-one correspondence control of a motor greatly increases the cost
